Introduction

Quick, easy and accurate nitrite testing at home!

From the Manufacturer:
Nitrite is produced in the aquarium in the forms of fish waste, uneaten food, and by nitrifying bacteria in your aquariums natural cycle as it breaks down ammonia. Low levels of nitrite inhibit respiration and suppress the immune system, while high levels cause suffocation in fish. The API NITRITE TEST KIT reads nitrite levels quickly and accurately in your tank, and tests parameters from 0 to 5 ppm.

Contains 180 tests and includes 1 test solution, easy-to-ready instructions, glass test tube and color chart.

Full instructions included in each testing kit. Use in conjunction with NITRATE and AMMONIA tests!
